(c) With reference to the Doppler Effect, write down an expression that relates the sound frequency fo heard by a stationary observer, when a sound source moving towards the observer at speed vs emits a frequency f. Based on the expression, state whether fs or fo is larger, and outline why this is the case. [4 marks]

    When the source of a wave and an observer move either towards or away from each other the observed frequency of the wave will be different from the frequency at which the wave is emitted. For example, if you are standing by the side of the road and a police car with a siren passes by, the frequency of the sound you hear will be higher when the car is moving towards you and lower when it is moving away...
